I've read & read several forums before I started but I end up bricking my SB6121. This is what I did...
USBJTAGNT_____SPI________ISP
Pin1----------------------------->R153 (R/S)
Pin3-------------->Pin15
Pin5-------------->Pin8
Pin9-------------->Pin16
Pin11------------>Pin7
Pin2------------->Pin10 (GRN)
I connected the jtag open up the program, jtag detected, plug the power on the modem, green light on, hit ID but flash was not detected. I tried letting the modem boot up, then connecting the jtag & still got the same result. I verified connection points and tried again. Once I power the modem the send, received & ethernet light are on but no power light? Modem is bricked!
I'm confused about the ISP point & what procedure to follow? I was going to used external power but since I have a known ISP point decided to go with this setup here...

BTW: I also tried Pin2 ISP (U7) to USBJATNT Pin1 but modem doesn't power.
